Video gamers who'd rather battle virtual villains than fight the flab can take heart. Use of the new Nintendo Wii can lead to weight loss.
After six weeks and 21 hours of total game play on Nintendo's new game console, Philadelphia resident Mickey DeLorenzo is nine pounds lighter and making a splash with his new svelte self.

But one Philadelphia man said they can actually help you lose weight, and he wants to prove you can give more than just your fingers a workout with the Nintendo Wii.

"The boxing game definitely generates the most sweat and calorie burn," said Mickey DeLorenzo, a self-described Nintendo freak since age 5.

DeLorenzo and his girlfriend had no idea how interactive it really is.

"After the first 10 minutes or so, we look over at each other. We're panting, we're sweating," he said.
...

"I would get into the game," he said. "I would punch, dodge, I would punch. And between rounds, if the person got knocked down, I'd hop on my toes and get ready."

He was dancing like a butterfly, stinging like a bee -- the whole deal.

It wasn't just boxing, either. He worked in a little bowling and some tennis, too. Slicing and drop-shotting Andre Agassi-style all over his virtual video opponents, DeLorenzo played the Wii hard -- 30 minutes a day for six straight weeks, constantly charting his progress, checking his body fat and measuring his waistline.

For the purpose of the experiment, he didn't change his eating habits.

So, how did he do? "Nine pounds total … 2 percent body-fat loss," he said.

DeLorenzo also dropped two pant sizes. Not too shabby for a video game workout program.

What do trainers think of his routine?

"If you're not the type of person who'll be motivated to get to the gym and you can find motivation in playing Nintendo Wii, good for you," said John Castello of Fitness Works in South Philadelphia.

This has been posted before, I think by DeLorenzo himself @ @. But this was awesome, I'm just worried that a bunch of developers are gonna try to publish some crappy ass fitness games. It'll be like this generations WWII games lol
